v PICTURE MOUNT Filed Jan. 27'I 1938 Q 'ga Si* m Sl l I fil \l \Q w Ny o w Patented Feb. 14, 1939 UNITED STATES PATENT OFFICE 1 Claim.

My present invention relates to picture mounts and more particularly to a novel structure for positioning and securing a picture or the like in a cardboard frame or mount.

5 The principal objects of my invention are to provide a form of mount that assures correct position of a picture when placed therein and that will secure it in position with its marginal portions covered and held against being torn or curled as often occurs with paper pictures merely pasted or otherwise secured on the surface of a cardboard back, as is the common practice with advertising calendars, etc.

Other objects are to provide a mount which permits removal of a picture therefrom without injury to either the mount or picture and substitution of another picture when desired, and to provide a construction which is durable and economical and particularly adapted for advertising matter such as art calendars, show cards, etc.

The foregoing advantages and improvements are attained by the novel manner of forming a picture receivingopening and retaining flap in a sheet of cardboard, or the like, described hereinafter and illustrated on the accompanying drawing, where:

Figure 1 is a face view of a picture mount embodying my invention;

Figure 2 is a rear view of the same; and

Figure 3 is a cross section, on anenlarged scale,

taken on the line 3--3 of Figure 2.

As one example of construction embodying my invention, there is illustrated on the drawing an art calendar comprising the usual rectangular oblong sheet of cardboard or the like I0 having a calendar pad Il mounted on its lower portion leaving its more extensive upper portion for receiving an art picture, advertising sign, or the like.

In the practice of my invention the picture receiving portion of the cardboard sheet or base is an opening therein, of whatever shape desired, formed by splitting the cardboard in such manner as to provide a flap I2 which is left joined to its base at one edge, there being provision made at said edge for aligning the picture with that edge in a manner to assure proper setting of the picture in the opening. In the form shown on the drawing, a rectangular picture opening has been formed by slitting the cardboard on three sides thereof leaving the flap I2 connected at its bottom edge I3 as an integral part of the cardboard base. At this edge short slits I4 are cut inwardly from the side slits or margins of the opening. These short slits form sharp corners at right angles to the side slits and are on the same level thereby forming straight seats or shoulders llrmly held in position as in a frame.

Ma (Fig. 3) on which the lower edge of the picture or insert sheet I5 rests as the cardboard is slightly distorted or bent rearwardly when the flap I2 is brought against the back of the insert sheet I5. This is well shown by Fig. 3 and constitutes an 5 essential feature of my invention as it not only serves to level an inserted picture but also eliminates the tendency of the material to tear along the lines of the side edges of the picture opening as the flap is being closed on a picture. It is 10 to be noted that the insert sheet or picture I5 used is of larger area than the picture opening provided by bending back the flap I 2. Therefore, the picture overlaps the side and upper margins of the opening and when the flap is closed or se- 15 cured against the back of the picture it will be A suitable fastening element for the flap l2, such as an adhesive tab I6, is provided for fastening the ap to the cardboard base proper. To enhance the 20 appearance of the picture, the margins of the opening on the front surface are preferably surrounded by a band, or beveled edge, Il' of contrasting color thus giving the eiect of a mat.

In the use of a picture mount constructed in accordance with my invention, a picture or the 25 like is quickly and accurately placed in the opening by simply bending the flap I2 back and seating the lower edge of the picture on the shoulders Illa. This automatically positions the picture accurately and when the ap is secured the picture 30 is smoothly held as the slits I4 also serve to free the lower corners of the ap l2 thereby preventing bulging of the lower edge of the picture due to cramping at the corners. Its removal is equally easy. Variations in the contour of the picture opening are of course possible without departure from my invention so long as the positioning slits I4 and shoulders Ilia, or the equivalent thereof, are provided at one edge of the picture opening.

What I claim as new is: 0

A picture mount comprising a cardboard base formed with a picture opening and an integral flap coextensive with said opening and joined to the base at the lower edge of the opening, the joined end of the ilap having free corners formed 45 by opposite short straight slits extending in alignment inwardly from its opposite sides and defining said lower edge of the opening thereby forming transversely spaced seats on said edge, a picture sheet of greater area than the opening posi- 5U tioned on the flap with one edge engaging said seats and displacing said free corners, its other marginal portions overlapping the rear surface of the base adjacent the opening, and means for securing the free portion of the flap to the base.
